The nurse is receiving report on a patient being admitted through the emergency department
The patient has emphysema and is receiving oxygen via a mask. He has a pulse oximetry reading ranging between 93% and 94%. The nurse anticipates that the patient is receiving oxygen via which type of mask commonly used for patients with COPD?
A) A nonrebreathing mask
B) A Venturi mask
C) A simple mask
D) A partial-rebreathing mask
Ans: B
Feedback: A Venturi mask is the most reliable and accurate method for delivering precise concentrations of oxygen through noninvasive means. The Venturi mask is used primarily for patients with COPD because it can accurately provide an appropriate level of supplemental oxygen, thus avoiding the risk of suppressing the hypoxic drive. This type of mask is constructed in a way that allows a constant flow of room air blended with a fixed flow of oxygen.
